What is operations management
bull Operations Management deals with the design and management of products processes services and supply chains It considers the acquisition development and utilization of resources that firms need to deliver the goods and services their clients want
bull The purvey of OM ranges from strategic to tactical and operational levels Representative strategic issues include determining the size and location of manufacturing plants deciding the structure of service or telecommunications networks and designing technology supply chains
bull Tactical issues include plant layout and structure project management methods and equipment selection and replacement Operational issues include production scheduling and control inventory management quality control and inspection traffic and materials handling and equipment maintenance policies
Production System
Manufacturing subsystem that includes all functions required to design produce distribute and service a manufactured product
bull Productionoperations management is the process which combines and transforms various resources used in the productionoperations subsystem of the organization into value added productservices in a controlled manner as per the policies of the organization Therefore it is that part of an organization which is concerned with the transformation of a range of inputs into the required (productsservices) having the requisite quality level The set of interrelated management activities which are involved in manufacturing certain products is called as production management If the same concept is extended to services management then the corresponding set of management activities is called as operations management
Production ConceptProduction function is that part of an organization which is concerned
with the transformation of a range of inputs into the required outputs (products) having the requisite quality level Production is defined as ldquothe step-by-step conversion of one form of material into another form through chemical or mechanical process to create or enhance the utility of the product to the userrdquo Thus production is a value addition process
At each stage of processing there will be value addition Edwood Buffa defines production as lsquoa process by which goods and services are createdrsquo Some examples of production are manufacturing custom-made products like boilers with a specific capacity constructing flats some structural fabrication works for selected customers etc and manufacturing standardized products like car bus motor cycle radio television etc
Production system
bull The production system of an organization is that part which produces products of an organization It is that activity whereby resources flowing within a defined system are combined and transformed in a controlled manner to add value in accordance with the policies communicated by management
A simplified production system is shown ashellip
The production system has the following characteristics
bull 1 Production is an organized activity so every production system has an objective
bull 2 The system transforms the various inputs to useful outputs
bull 3 It does not operate in isolation from the other organization system
bull 4 There exists a feedback about the activities which is essential to control and improve system performance
bull Production management is a process of planning organizing directing and controlling the activities of the production function It combines and transforms various resources used in the production subsystem of the organization into value added product in a controlled manner as per the policies of the organization
ES Buffa defines production management as ldquoProduction management deals with decision making related to production processes so that the resulting goods or services are produced according to specifications in the amount and by the schedule demanded and out of minimum costrdquo
Objectives of Production Management
The objective of the production management is lsquoto produce goods services of right quality and quantity at the right time and right manufacturing costrsquo
bull 1 RIGHT QUALITY The quality of product is established based upon the customers
needs The right quality is not necessarily best quality It is determined by the cost of the product and the technical characteristics as suited to the specific requirements
bull 2 RIGHT QUANTITYbull The manufacturing organization should produce the products in
right number If they are produced in excess of demand the capital will block up in the form of inventory and if the quantity is produced in short of demand leads to shortage of products
bull 3 RIGHT TIMEbull Timeliness of delivery is one of the important
parameter to judge the effectiveness of production department So the production department has to make the optimal utilization of input resources to achieve its objective
bull 4 RIGHT MANUFACTURING COSTbull Manufacturing costs are established before the
product is actually manufactured Hence all attempts should be made to produce the products at pre-established cost so as to reduce the variation between actual and the standard (pre-established) cost
Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need
to be made) KPIs (employee appraisals) Transformation of information (eg Hygiene laws and OHampS
change in such a way that it is easily understood by everyone else Posters up the wall sign over hand wash basin on how to properly wash your hands etc)
In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

outputs that customers consume overtime jobs that use less labour and more equipment little customer contact no customer participation in the conversion process (in production) and sophisticated methods for measuring production activities and resource consumption as product are made
bull Service is characterised by intangible outputs outputs that customers consumes immediately jobs that use more labour and less equipment direct consumer contact frequent customer participation in the conversion process and elementary methods for measuring conversion activities and resource consumption Some services are equipment based namely rail-road services telephone services and some are people based namely tax consultant services hair styling
Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

Historical Development of OM
bull For over two centuries operations and production management has been recognised as an important factor in a countryrsquos economic growth The traditional view of manufacturing management began in eighteenth century when Adam Smith recognised the economic benefits of specialisation of labour He recommended breaking of jobs down into subtasks and recognises workers to specialised tasks in which they would become highly skilled and efficient In the early twentieth century FW Taylor implemented Smithrsquos theories and developed scientific management From then till 1930 many techniques were developed prevailing the traditional view Brief information about the contributions to manufacturing management is shown below

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability
In fact these directly relate to the competitiveness of the organization both nationally and internationally Modern developments in better tools and techniques methods and systems like Automation Flexible manufacturing CAD

bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

What is operations management
bull Operations Management deals with the design and management of products processes services and supply chains It considers the acquisition development and utilization of resources that firms need to deliver the goods and services their clients want
bull The purvey of OM ranges from strategic to tactical and operational levels Representative strategic issues include determining the size and location of manufacturing plants deciding the structure of service or telecommunications networks and designing technology supply chains
bull Tactical issues include plant layout and structure project management methods and equipment selection and replacement Operational issues include production scheduling and control inventory management quality control and inspection traffic and materials handling and equipment maintenance policies
Production System
Manufacturing subsystem that includes all functions required to design produce distribute and service a manufactured product
bull Productionoperations management is the process which combines and transforms various resources used in the productionoperations subsystem of the organization into value added productservices in a controlled manner as per the policies of the organization Therefore it is that part of an organization which is concerned with the transformation of a range of inputs into the required (productsservices) having the requisite quality level The set of interrelated management activities which are involved in manufacturing certain products is called as production management If the same concept is extended to services management then the corresponding set of management activities is called as operations management
Production ConceptProduction function is that part of an organization which is concerned
with the transformation of a range of inputs into the required outputs (products) having the requisite quality level Production is defined as ldquothe step-by-step conversion of one form of material into another form through chemical or mechanical process to create or enhance the utility of the product to the userrdquo Thus production is a value addition process
At each stage of processing there will be value addition Edwood Buffa defines production as lsquoa process by which goods and services are createdrsquo Some examples of production are manufacturing custom-made products like boilers with a specific capacity constructing flats some structural fabrication works for selected customers etc and manufacturing standardized products like car bus motor cycle radio television etc
Production system
bull The production system of an organization is that part which produces products of an organization It is that activity whereby resources flowing within a defined system are combined and transformed in a controlled manner to add value in accordance with the policies communicated by management
A simplified production system is shown ashellip
The production system has the following characteristics
bull 1 Production is an organized activity so every production system has an objective
bull 2 The system transforms the various inputs to useful outputs
bull 3 It does not operate in isolation from the other organization system
bull 4 There exists a feedback about the activities which is essential to control and improve system performance
bull Production management is a process of planning organizing directing and controlling the activities of the production function It combines and transforms various resources used in the production subsystem of the organization into value added product in a controlled manner as per the policies of the organization
ES Buffa defines production management as ldquoProduction management deals with decision making related to production processes so that the resulting goods or services are produced according to specifications in the amount and by the schedule demanded and out of minimum costrdquo
Objectives of Production Management
The objective of the production management is lsquoto produce goods services of right quality and quantity at the right time and right manufacturing costrsquo
bull 1 RIGHT QUALITY The quality of product is established based upon the customers
needs The right quality is not necessarily best quality It is determined by the cost of the product and the technical characteristics as suited to the specific requirements
bull 2 RIGHT QUANTITYbull The manufacturing organization should produce the products in
right number If they are produced in excess of demand the capital will block up in the form of inventory and if the quantity is produced in short of demand leads to shortage of products
bull 3 RIGHT TIMEbull Timeliness of delivery is one of the important
parameter to judge the effectiveness of production department So the production department has to make the optimal utilization of input resources to achieve its objective
bull 4 RIGHT MANUFACTURING COSTbull Manufacturing costs are established before the
product is actually manufactured Hence all attempts should be made to produce the products at pre-established cost so as to reduce the variation between actual and the standard (pre-established) cost
Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need
to be made) KPIs (employee appraisals) Transformation of information (eg Hygiene laws and OHampS
change in such a way that it is easily understood by everyone else Posters up the wall sign over hand wash basin on how to properly wash your hands etc)
In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

outputs that customers consume overtime jobs that use less labour and more equipment little customer contact no customer participation in the conversion process (in production) and sophisticated methods for measuring production activities and resource consumption as product are made
bull Service is characterised by intangible outputs outputs that customers consumes immediately jobs that use more labour and less equipment direct consumer contact frequent customer participation in the conversion process and elementary methods for measuring conversion activities and resource consumption Some services are equipment based namely rail-road services telephone services and some are people based namely tax consultant services hair styling
Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans

bull Productionoperations management is the process which combines and transforms various resources used in the productionoperations subsystem of the organization into value added productservices in a controlled manner as per the policies of the organization Therefore it is that part of an organization which is concerned with the transformation of a range of inputs into the required (productsservices) having the requisite quality level The set of interrelated management activities which are involved in manufacturing certain products is called as production management If the same concept is extended to services management then the corresponding set of management activities is called as operations management
Production ConceptProduction function is that part of an organization which is concerned
with the transformation of a range of inputs into the required outputs (products) having the requisite quality level Production is defined as ldquothe step-by-step conversion of one form of material into another form through chemical or mechanical process to create or enhance the utility of the product to the userrdquo Thus production is a value addition process
At each stage of processing there will be value addition Edwood Buffa defines production as lsquoa process by which goods and services are createdrsquo Some examples of production are manufacturing custom-made products like boilers with a specific capacity constructing flats some structural fabrication works for selected customers etc and manufacturing standardized products like car bus motor cycle radio television etc
Production system
bull The production system of an organization is that part which produces products of an organization It is that activity whereby resources flowing within a defined system are combined and transformed in a controlled manner to add value in accordance with the policies communicated by management
A simplified production system is shown ashellip
The production system has the following characteristics
bull 1 Production is an organized activity so every production system has an objective
bull 2 The system transforms the various inputs to useful outputs
bull 3 It does not operate in isolation from the other organization system
bull 4 There exists a feedback about the activities which is essential to control and improve system performance
bull Production management is a process of planning organizing directing and controlling the activities of the production function It combines and transforms various resources used in the production subsystem of the organization into value added product in a controlled manner as per the policies of the organization
ES Buffa defines production management as ldquoProduction management deals with decision making related to production processes so that the resulting goods or services are produced according to specifications in the amount and by the schedule demanded and out of minimum costrdquo
Objectives of Production Management
The objective of the production management is lsquoto produce goods services of right quality and quantity at the right time and right manufacturing costrsquo
bull 1 RIGHT QUALITY The quality of product is established based upon the customers
needs The right quality is not necessarily best quality It is determined by the cost of the product and the technical characteristics as suited to the specific requirements
bull 2 RIGHT QUANTITYbull The manufacturing organization should produce the products in
right number If they are produced in excess of demand the capital will block up in the form of inventory and if the quantity is produced in short of demand leads to shortage of products
bull 3 RIGHT TIMEbull Timeliness of delivery is one of the important
parameter to judge the effectiveness of production department So the production department has to make the optimal utilization of input resources to achieve its objective
bull 4 RIGHT MANUFACTURING COSTbull Manufacturing costs are established before the
product is actually manufactured Hence all attempts should be made to produce the products at pre-established cost so as to reduce the variation between actual and the standard (pre-established) cost
Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need
to be made) KPIs (employee appraisals) Transformation of information (eg Hygiene laws and OHampS
change in such a way that it is easily understood by everyone else Posters up the wall sign over hand wash basin on how to properly wash your hands etc)
In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability

Historical Development of OM
bull For over two centuries operations and production management has been recognised as an important factor in a countryrsquos economic growth The traditional view of manufacturing management began in eighteenth century when Adam Smith recognised the economic benefits of specialisation of labour He recommended breaking of jobs down into subtasks and recognises workers to specialised tasks in which they would become highly skilled and efficient In the early twentieth century FW Taylor implemented Smithrsquos theories and developed scientific management From then till 1930 many techniques were developed prevailing the traditional view Brief information about the contributions to manufacturing management is shown below

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability
In fact these directly relate to the competitiveness of the organization both nationally and internationally Modern developments in better tools and techniques methods and systems like Automation Flexible manufacturing CAD

bull Productionoperations management is the process which combines and transforms various resources used in the productionoperations subsystem of the organization into value added productservices in a controlled manner as per the policies of the organization Therefore it is that part of an organization which is concerned with the transformation of a range of inputs into the required (productsservices) having the requisite quality level The set of interrelated management activities which are involved in manufacturing certain products is called as production management If the same concept is extended to services management then the corresponding set of management activities is called as operations management
Production ConceptProduction function is that part of an organization which is concerned
with the transformation of a range of inputs into the required outputs (products) having the requisite quality level Production is defined as ldquothe step-by-step conversion of one form of material into another form through chemical or mechanical process to create or enhance the utility of the product to the userrdquo Thus production is a value addition process
At each stage of processing there will be value addition Edwood Buffa defines production as lsquoa process by which goods and services are createdrsquo Some examples of production are manufacturing custom-made products like boilers with a specific capacity constructing flats some structural fabrication works for selected customers etc and manufacturing standardized products like car bus motor cycle radio television etc
Production system
bull The production system of an organization is that part which produces products of an organization It is that activity whereby resources flowing within a defined system are combined and transformed in a controlled manner to add value in accordance with the policies communicated by management
A simplified production system is shown ashellip
The production system has the following characteristics
bull 1 Production is an organized activity so every production system has an objective
bull 2 The system transforms the various inputs to useful outputs
bull 3 It does not operate in isolation from the other organization system
bull 4 There exists a feedback about the activities which is essential to control and improve system performance
bull Production management is a process of planning organizing directing and controlling the activities of the production function It combines and transforms various resources used in the production subsystem of the organization into value added product in a controlled manner as per the policies of the organization
ES Buffa defines production management as ldquoProduction management deals with decision making related to production processes so that the resulting goods or services are produced according to specifications in the amount and by the schedule demanded and out of minimum costrdquo
Objectives of Production Management
The objective of the production management is lsquoto produce goods services of right quality and quantity at the right time and right manufacturing costrsquo
bull 1 RIGHT QUALITY The quality of product is established based upon the customers
needs The right quality is not necessarily best quality It is determined by the cost of the product and the technical characteristics as suited to the specific requirements
bull 2 RIGHT QUANTITYbull The manufacturing organization should produce the products in
right number If they are produced in excess of demand the capital will block up in the form of inventory and if the quantity is produced in short of demand leads to shortage of products
bull 3 RIGHT TIMEbull Timeliness of delivery is one of the important
parameter to judge the effectiveness of production department So the production department has to make the optimal utilization of input resources to achieve its objective
bull 4 RIGHT MANUFACTURING COSTbull Manufacturing costs are established before the
product is actually manufactured Hence all attempts should be made to produce the products at pre-established cost so as to reduce the variation between actual and the standard (pre-established) cost
Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need
to be made) KPIs (employee appraisals) Transformation of information (eg Hygiene laws and OHampS
change in such a way that it is easily understood by everyone else Posters up the wall sign over hand wash basin on how to properly wash your hands etc)
In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

outputs that customers consume overtime jobs that use less labour and more equipment little customer contact no customer participation in the conversion process (in production) and sophisticated methods for measuring production activities and resource consumption as product are made
bull Service is characterised by intangible outputs outputs that customers consumes immediately jobs that use more labour and less equipment direct consumer contact frequent customer participation in the conversion process and elementary methods for measuring conversion activities and resource consumption Some services are equipment based namely rail-road services telephone services and some are people based namely tax consultant services hair styling
Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

Production ConceptProduction function is that part of an organization which is concerned
with the transformation of a range of inputs into the required outputs (products) having the requisite quality level Production is defined as ldquothe step-by-step conversion of one form of material into another form through chemical or mechanical process to create or enhance the utility of the product to the userrdquo Thus production is a value addition process
At each stage of processing there will be value addition Edwood Buffa defines production as lsquoa process by which goods and services are createdrsquo Some examples of production are manufacturing custom-made products like boilers with a specific capacity constructing flats some structural fabrication works for selected customers etc and manufacturing standardized products like car bus motor cycle radio television etc
Production system
bull The production system of an organization is that part which produces products of an organization It is that activity whereby resources flowing within a defined system are combined and transformed in a controlled manner to add value in accordance with the policies communicated by management
A simplified production system is shown ashellip
The production system has the following characteristics
bull 1 Production is an organized activity so every production system has an objective
bull 2 The system transforms the various inputs to useful outputs
bull 3 It does not operate in isolation from the other organization system
bull 4 There exists a feedback about the activities which is essential to control and improve system performance
bull Production management is a process of planning organizing directing and controlling the activities of the production function It combines and transforms various resources used in the production subsystem of the organization into value added product in a controlled manner as per the policies of the organization
ES Buffa defines production management as ldquoProduction management deals with decision making related to production processes so that the resulting goods or services are produced according to specifications in the amount and by the schedule demanded and out of minimum costrdquo
Objectives of Production Management
The objective of the production management is lsquoto produce goods services of right quality and quantity at the right time and right manufacturing costrsquo
bull 1 RIGHT QUALITY The quality of product is established based upon the customers
needs The right quality is not necessarily best quality It is determined by the cost of the product and the technical characteristics as suited to the specific requirements
bull 2 RIGHT QUANTITYbull The manufacturing organization should produce the products in
right number If they are produced in excess of demand the capital will block up in the form of inventory and if the quantity is produced in short of demand leads to shortage of products
bull 3 RIGHT TIMEbull Timeliness of delivery is one of the important
parameter to judge the effectiveness of production department So the production department has to make the optimal utilization of input resources to achieve its objective
bull 4 RIGHT MANUFACTURING COSTbull Manufacturing costs are established before the
product is actually manufactured Hence all attempts should be made to produce the products at pre-established cost so as to reduce the variation between actual and the standard (pre-established) cost
Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need

bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

manufacturing techniques and engaging in continual dialogue with customers
bull Benefits of Mass Customizationndash Creates an important relationship between the firm and
the customer in providing loyalty-building value to the customer and in garnering valuable market information for the firm
CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability
In fact these directly relate to the competitiveness of the organization both nationally and internationally Modern developments in better tools and techniques methods and systems like Automation Flexible manufacturing CAD

Production system
bull The production system of an organization is that part which produces products of an organization It is that activity whereby resources flowing within a defined system are combined and transformed in a controlled manner to add value in accordance with the policies communicated by management
A simplified production system is shown ashellip
The production system has the following characteristics
bull 1 Production is an organized activity so every production system has an objective
bull 2 The system transforms the various inputs to useful outputs
bull 3 It does not operate in isolation from the other organization system
bull 4 There exists a feedback about the activities which is essential to control and improve system performance
bull Production management is a process of planning organizing directing and controlling the activities of the production function It combines and transforms various resources used in the production subsystem of the organization into value added product in a controlled manner as per the policies of the organization
ES Buffa defines production management as ldquoProduction management deals with decision making related to production processes so that the resulting goods or services are produced according to specifications in the amount and by the schedule demanded and out of minimum costrdquo
Objectives of Production Management
The objective of the production management is lsquoto produce goods services of right quality and quantity at the right time and right manufacturing costrsquo
bull 1 RIGHT QUALITY The quality of product is established based upon the customers
needs The right quality is not necessarily best quality It is determined by the cost of the product and the technical characteristics as suited to the specific requirements
bull 2 RIGHT QUANTITYbull The manufacturing organization should produce the products in
right number If they are produced in excess of demand the capital will block up in the form of inventory and if the quantity is produced in short of demand leads to shortage of products
bull 3 RIGHT TIMEbull Timeliness of delivery is one of the important
parameter to judge the effectiveness of production department So the production department has to make the optimal utilization of input resources to achieve its objective
bull 4 RIGHT MANUFACTURING COSTbull Manufacturing costs are established before the
product is actually manufactured Hence all attempts should be made to produce the products at pre-established cost so as to reduce the variation between actual and the standard (pre-established) cost
Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need
to be made) KPIs (employee appraisals) Transformation of information (eg Hygiene laws and OHampS
change in such a way that it is easily understood by everyone else Posters up the wall sign over hand wash basin on how to properly wash your hands etc)
In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right

The production system has the following characteristics
bull 1 Production is an organized activity so every production system has an objective
bull 2 The system transforms the various inputs to useful outputs
bull 3 It does not operate in isolation from the other organization system
bull 4 There exists a feedback about the activities which is essential to control and improve system performance
bull Production management is a process of planning organizing directing and controlling the activities of the production function It combines and transforms various resources used in the production subsystem of the organization into value added product in a controlled manner as per the policies of the organization
ES Buffa defines production management as ldquoProduction management deals with decision making related to production processes so that the resulting goods or services are produced according to specifications in the amount and by the schedule demanded and out of minimum costrdquo
Objectives of Production Management
The objective of the production management is lsquoto produce goods services of right quality and quantity at the right time and right manufacturing costrsquo
bull 1 RIGHT QUALITY The quality of product is established based upon the customers
needs The right quality is not necessarily best quality It is determined by the cost of the product and the technical characteristics as suited to the specific requirements
bull 2 RIGHT QUANTITYbull The manufacturing organization should produce the products in
right number If they are produced in excess of demand the capital will block up in the form of inventory and if the quantity is produced in short of demand leads to shortage of products
bull 3 RIGHT TIMEbull Timeliness of delivery is one of the important
parameter to judge the effectiveness of production department So the production department has to make the optimal utilization of input resources to achieve its objective
bull 4 RIGHT MANUFACTURING COSTbull Manufacturing costs are established before the
product is actually manufactured Hence all attempts should be made to produce the products at pre-established cost so as to reduce the variation between actual and the standard (pre-established) cost
Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need
to be made) KPIs (employee appraisals) Transformation of information (eg Hygiene laws and OHampS
change in such a way that it is easily understood by everyone else Posters up the wall sign over hand wash basin on how to properly wash your hands etc)
In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

Historical Development of OM
bull For over two centuries operations and production management has been recognised as an important factor in a countryrsquos economic growth The traditional view of manufacturing management began in eighteenth century when Adam Smith recognised the economic benefits of specialisation of labour He recommended breaking of jobs down into subtasks and recognises workers to specialised tasks in which they would become highly skilled and efficient In the early twentieth century FW Taylor implemented Smithrsquos theories and developed scientific management From then till 1930 many techniques were developed prevailing the traditional view Brief information about the contributions to manufacturing management is shown below

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability
In fact these directly relate to the competitiveness of the organization both nationally and internationally Modern developments in better tools and techniques methods and systems like Automation Flexible manufacturing CAD

Objectives of Production Management
The objective of the production management is lsquoto produce goods services of right quality and quantity at the right time and right manufacturing costrsquo
bull 1 RIGHT QUALITY The quality of product is established based upon the customers
needs The right quality is not necessarily best quality It is determined by the cost of the product and the technical characteristics as suited to the specific requirements
bull 2 RIGHT QUANTITYbull The manufacturing organization should produce the products in
right number If they are produced in excess of demand the capital will block up in the form of inventory and if the quantity is produced in short of demand leads to shortage of products
bull 3 RIGHT TIMEbull Timeliness of delivery is one of the important
parameter to judge the effectiveness of production department So the production department has to make the optimal utilization of input resources to achieve its objective
bull 4 RIGHT MANUFACTURING COSTbull Manufacturing costs are established before the
product is actually manufactured Hence all attempts should be made to produce the products at pre-established cost so as to reduce the variation between actual and the standard (pre-established) cost
Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need
to be made) KPIs (employee appraisals) Transformation of information (eg Hygiene laws and OHampS
change in such a way that it is easily understood by everyone else Posters up the wall sign over hand wash basin on how to properly wash your hands etc)
In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

outputs that customers consume overtime jobs that use less labour and more equipment little customer contact no customer participation in the conversion process (in production) and sophisticated methods for measuring production activities and resource consumption as product are made
bull Service is characterised by intangible outputs outputs that customers consumes immediately jobs that use more labour and less equipment direct consumer contact frequent customer participation in the conversion process and elementary methods for measuring conversion activities and resource consumption Some services are equipment based namely rail-road services telephone services and some are people based namely tax consultant services hair styling
Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability
In fact these directly relate to the competitiveness of the organization both nationally and internationally Modern developments in better tools and techniques methods and systems like Automation Flexible manufacturing CAD

Transformation Process Organisations are managed systems that are generally made up of interrelated and
interdependent parts that process inputs raw material time equipment information technology labour personnel capital money etc
into outputs usable plans contingency plans strategies controls action efficient operations processes
bull This is achieved through the transformational process
Input - processes - outputs - outcomes (goal achievement customer amp stakeholder satisfaction)
The core processes (how do you plan your output) would be through Consultation (daily service briefings weekly meetings) Collaboration (teamwork consulting with staff) Goal setting (management to see if improvements changes need
to be made) KPIs (employee appraisals) Transformation of information (eg Hygiene laws and OHampS
change in such a way that it is easily understood by everyone else Posters up the wall sign over hand wash basin on how to properly wash your hands etc)
In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability
In fact these directly relate to the competitiveness of the organization both nationally and internationally Modern developments in better tools and techniques methods and systems like Automation Flexible manufacturing CAD

In other words
bull The Transformation Processbull All operations produce products and services by
changing inputs into outputs They do this by using the lsquoinput-transformation-output process In other words operations are processes that take in a set of input resources which are used to transform something or are transformed themselves into outputs of products and services
bull There are two categories of inputs in any operations processes transformed and transforming resources
Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)

Transformed resources are the resources that are treated transformed or converted in the process The three main types of transformed resources include
bull Materials involves transforming either physically (eg manufacturing) by location (eg transportation) by ownership (eg retail) or by storage (eg warehousing)
bull Information This can be transformed by property (eg accountants) by possession (eg market research) by storage (eg libraries) or by location (eg telecommunications)
bull Customers They can be transformed either physically (eg hairdressers) by storage (eg hotels) by location (egairlines) by physiological state (eg hospitals) or by psychological state (eg entertainment)
bull The other set of inputs to any operations process are transforming resources These are the resources which act on or carry out the transformation process There are two main types of transforming resources
bull Facilities - the buildings equipment plant and process technology of the operation
bull Staff - includes all the people involved in the operations process
bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

bull The exact nature of both facilities and staff will differ between operations For example most staff employed in a factory assembling air conditioners may not need a very high level of technical skills In contrast most staff employed by an accounting firm will require a higher level skills and qualifications Similarly the facilities in both types of work would differ quite significantly
bull Although products and services are different sometimes it can be hard to differentiate between the two Therefore as a general guideline products are usually tangible while services are intangible That is you can physically touch a product such as a computer but you cannot touch a consultancy advice Also services usually have a shorter stored life while products can usually be stored for a period of time
Transformation in simplest termsbull Transformation processesbull A transformation process is any activity or group of activities that takes one
or more inputs transforms and adds value to them and provides outputs for customers or clients Where the inputs are raw materials it is relatively easy to identify the transformation involved as when milk is transformed into cheese and butter Where the inputs are information or people the nature of the transformation may be less obvious For example a hospital transforms ill patients (the input) into healthy patients (the output)
Transformation processes includebull changes in the physical characteristics of materials or customersbull changes in the location of materials information or customersbull changes in the ownership of materials or informationbull storage or accommodation of materials information or customersbull changes in the purpose or form of informationbull changes in the physiological or psychological state of customers
bull Often all three types of input ndash materials information and customers ndash are transformed by the same organisation For example withdrawing money from a bank account involves information about the customers account materials such as cheques and currency and the customer Treating a patient in hospital involves not only the lsquocustomersrsquo state of health but also any materials used in treatment and information about the patient
One useful way of categorising different types of transformation is into
bull manufacture ndash the physical creation of products (for example cars)bull transport ndash the movement of materials or customers (for example
a taxi service)bull supply ndash change in ownership of goods (for example in retailing)bull service ndash the treatment of customers or the storage of materials
(for example hospital wards warehouses)
bull Several different transformations are usually required to produce a good or service The overall transformation can be described as the macro operation and the more detailed transformations within this macro operation as micro operations For example the macro operation in a brewery is making beer (see Figure) The micro operations include
bull milling the malted barley into gristbull mixing the grist with hot water to form wortbull cooling the wort and transferring it to the fermentation vesselbull adding yeast to the wort and fermenting the liquid into beerbull filtering the beer to remove the spent yeastbull decanting the beer into casks or bottles

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

Historical Development of OM
bull For over two centuries operations and production management has been recognised as an important factor in a countryrsquos economic growth The traditional view of manufacturing management began in eighteenth century when Adam Smith recognised the economic benefits of specialisation of labour He recommended breaking of jobs down into subtasks and recognises workers to specialised tasks in which they would become highly skilled and efficient In the early twentieth century FW Taylor implemented Smithrsquos theories and developed scientific management From then till 1930 many techniques were developed prevailing the traditional view Brief information about the contributions to manufacturing management is shown below

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability

Historical Development of OM
bull For over two centuries operations and production management has been recognised as an important factor in a countryrsquos economic growth The traditional view of manufacturing management began in eighteenth century when Adam Smith recognised the economic benefits of specialisation of labour He recommended breaking of jobs down into subtasks and recognises workers to specialised tasks in which they would become highly skilled and efficient In the early twentieth century FW Taylor implemented Smithrsquos theories and developed scientific management From then till 1930 many techniques were developed prevailing the traditional view Brief information about the contributions to manufacturing management is shown below

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system
Optimum Good Better operations management can improve(i) Efficiency of operation system to do things right and broader
concept(ii) Effectiveness of operation system refers to doing right things that
is seven rights they areRight operation Right Quantity Right Quality Right Supplier or Right
Vendor Right Time Right Place and Right PriceBasically efficiency and effectiveness of the operations system can
be measured by four dimensionsThey are (i) Cost (ii) Quality (iii) Dependability and (iv) Reliability
In fact these directly relate to the competitiveness of the organization both nationally and internationally Modern developments in better tools and techniques methods and systems like Automation Flexible manufacturing CAD

Function of Production DepartmentManagement
bull (i) Materials The selection of materials for the product Production manager must have sound Knowledge of materials and their properties so that he can select appropriate materials for his product Research on materials is necessary to find alternatives to satisfy the changing needs of the design in the product and availability of material resumes
bull (ii) Methods Finding the best method for the process to search for the methods to suit the available resources identifying the sequence of process are some of the activities of Production Management
bull (iii) Machines and Equipment Selection of suitable machinery for the process desired designing the maintenance policy and design of layout of machines are taken care of by the Production Management department
bull (iv) Estimating To fix up the Production targets and delivery dates and to keep the production costs at minimum production management department does a thorough estimation of Production times and production costs In competitive situation this will help the management to decide what should be done in arresting the costs at desired level
bull (v) Loading and Scheduling The Production Management department has to draw the time table for various production activities specifying when to start and when to finish the process required It also has to draw the timings of materials movement and plan the activities of manpower The scheduling is to be done keeping in mind the loads on hand and capacities of facilities available
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

CRITERIA OF PERFORMANCE Three aims of performance of the Production and Operations Management
system may be identifiedThey are(a) Effectiveness (b) Customer satisfaction (c) EfficiencyThe case of Efficiency is productive utilization of resources is clear Whether
the organization is in lsquoprivate sectorrsquo or in the lsquopublic sectorrsquo is a lsquomanufacturing or lsquonon-manufacturingrsquo organization or a lsquoprofitrsquo or a lsquonon-profitrsquo organization the optimal utilization of resource inputs is always a desired objective The effectiveness has more dimensions to it It involves optimality in the fulfillment of multiple objectives with a possible prioritization within the objectives Modern production and operations management has to serve the target customers the people working within as also the region country or society at large Thus Production Operations Management system has not only to be profitable and or efficient but must necessarily satisfy many more customers This effectiveness has to be again viewed in terms of the short and long-term horizons depending upon the operations system

bull Costbull Qualitybull Flexibilitybull Speed
bull (vi) Routing This is the most important function of Production Management department The Routing consists of fixing the flow lines for various raw materials components etc from the stores to the packing of finished product so that all concerned knows what exactly is happening on the shop floor
bull (vii) Despatching The Production Management department has to prepare various documents such as Job Cards Route sheets Move Cards Inspection Cards for each and every component of the product These are prepared in a set of five copies These documents are to be released from Production Management department to give green signal for starting the production The activities of the shop floor will follow the instructions given in these documents Activity of releasing the document is known as dispatching
bull (viii) Expediting or Follow up Once the documents are dispatched the management wants to know whether the activities are being carried out as per the plans or not Expediting engineers go round the production floor along with the plans compare the actual with the plan and feed back the progress of the work to the management This will help the management to evaluate the plans
bull (ix) Inspection Here inspection is generally concerned with the inspection activities during production but a separate quality control department does the quality inspection which is not under the control of Production Management This is true because if the quality inspection is given to production Management then there is a chance of qualifying the defective products also For example Teaching and examining of students is given to the same person then there is a possibility of passing Production and Operations Management all the students in the first grade To avoid this situation an external person does correction of answer scripts so that the quality of answers are correctly judged
bull (x) Evaluation The Production department must evaluate itself and its contribution in fulfilling the corporate objectives and the departmental objectives This is necessary for setting up the standards for future What ever may be the size of the firm Production management department alone must do Routing Scheduling Loading Dispatching and expediting This is because this department knows very well regarding materials Methods and available resources etc If the firms are small all the above-mentioned functions (i to x) are to be carried out by Production Management Department In medium sized firms in addition to Routing Scheduling and Loading Dispatching and expediting some more functions like Methods Machines may be under the control of Production Management Department In large firms there will be Separate departments for Methods Machines Materials and others but routing loading and scheduling are the sole functions of Production Management All the above ten functions are categorized in three stage that is Preplanning Planning and control stages as

Historical Development of OM
bull For over two centuries operations and production management has been recognised as an important factor in a countryrsquos economic growth The traditional view of manufacturing management began in eighteenth century when Adam Smith recognised the economic benefits of specialisation of labour He recommended breaking of jobs down into subtasks and recognises workers to specialised tasks in which they would become highly skilled and efficient In the early twentieth century FW Taylor implemented Smithrsquos theories and developed scientific management From then till 1930 many techniques were developed prevailing the traditional view Brief information about the contributions to manufacturing management is shown below
